我正在将 Spring Data Neo4j 与 Springboot 一起使用，并且该应用程序可以正常工作。

但是，如果可能，我想在启动时删除大量警告。

是什么让它如此不开心？

【问题讨论】：

你有想过这个吗？
不，我现在只是过滤那些:(
其实，我终于解决了... :)。我会发布答案...

标签： spring-boot neo4j spring-data-neo4j

【解决方案1】：

有同样的问题（SpringBoot 2.2.2 依赖 spring-boot-starter-data-neo4j）。通过向主 @SpringBootApplication 带注释的应用程序类添加 both 注释来消除警告和缩小实体/模型类的扫描范围：

@EnableNeo4jRepositories("my.project.reposoitory")
@EntityScan("my.project.model")

避免需要单独的@Config 类/覆盖 SpringBoot 自动配置。请参阅docs。

更新： 将 Spring Boot 版本提高到 2.2.4.RELEASE，因为我在从 Neo4jRepository 声明性方法返回任何数据时遇到问题。怀疑这与 tx 相关，会引发缺陷。

【讨论】：

根据一些设置教程，我已经拥有@EnableNeo4jRepositories。添加@EntityScan 也为我消除了错误。

【解决方案2】：

我为我的应用程序解决此错误的最简单方法是在application.properties 文件中添加以下行

logging.level.org.spring.data.neo4j.mapping.*=ERROR

【讨论】：

【解决方案3】：

我遇到了同样的问题，2天后，我终于弄明白了......

我的 pom.xml 看起来像这样：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-neo4j</artifactId>
        <version>2.2.2.RELEASE</version> <!--$NO-MVN-MAN-VER$-->
    </dependency>

然后通常您的应用程序属性中会包含用户名和密码：

spring.data.neo4j.open-in-view=false
spring.data.neo4j.uri=bolt://localhost
spring.data.neo4j.username=neo4j
spring.data.neo4j.password=xxx

您还将获得启用电话：

@EnableNeo4jRepositories

默认情况下，Neo4j 代码似乎正在扫描您应用中的所有类，但您可以覆盖此行为：

创建一个配置类并将您的 EnableNeo4jRepositories 移动到那里
指定您的 repo 基础包
指定您的模型基础包

现在 Neo4j 代码知道只扫描 repo 和模型包。这是我的电影数据集的配置类：

@Configuration
@EnableNeo4jRepositories(basePackages="org.xx.yy.movies.repositories")
public class MoviesDataSourceConfig {

    @Bean
    public org.neo4j.ogm.config.Configuration getConfiguration() {
        org.neo4j.ogm.config.Configuration config = new Builder()
                .uri("bolt://username:password@localhost:7687").
                build();
        return config;
    }

    @Bean
    public Neo4jTransactionManager transactionManager() {
        return new Neo4jTransactionManager(sessionFactory());
    }

    @Bean
    public SessionFactory sessionFactory() {
        return new SessionFactory(getConfiguration(), "org.xx.yy.movies.models");
    }
}

请注意，您需要在 uri 中指定用户名和密码...这仍然是 POC 代码，但我只是将它们从 spring.data.neo4j 属性中提取出来以进行生产。

没有更多警告消息！
